Holy crap, what a nightmare to get back together! Took me and my wife three hours to get it back together. No way I could do it alone; gave up after the first two hours. In the tutorial pictures the extractor spring and plunger sit almost flush with the hole they recess into, and so the extractor just slides into place. I wish! On my Norinco bolt the extractor spring and plunger stick way far out. This means you have to manually compress the extractor spring and plunger at the same time as you are manually compressing the ejector spring and ejector and pushing in the extractor to lock it all in place. Craziest system I've ever seen! I had pieces flying all over the place like twenty times. In the end we had to use a set of needle nose vise grips to push in the extractor spring and plunger in and lock them in place, then push in the ejector spring and ejector with the M14 tool, then use another huge pair of vise grips to sqeeze the ejector in place and force off the first pair of vise grips as the ejector covered over the extractor spring and plunger. I say again, craziest system I've ever seen. And I can't believe how many times we managed to find the springs and plungers etc after they went flying all over. The next time I dissasemble one of those bolts will be right after hell freezes over.
